Actually I could not find any papers talking about pigmentation expression in Nepenthes when I searched on my schools scholarly article database which includes many of the major scholarly article databases. My reasoning is that betalains are rare in the plant kingdom compared to anthocyanins when it comes to pigmentation expression.

As corky said, Dave has mentioned twice that anthocyanins haven't been found in Nepenthes. Im sure if this discussion was brought up on the PP forums he could find an article or two.
all this talk of pigmentations has me dozing off.
wake me when the eddie pics continue
That pitcher popped solid green, and just keeps getting more and more color. I think it just comes down to how long it's been exposed to the light.
my seed grown from the batch pops em at an orange and then they end up dark red. even while inflating they are not green. very cool that yours is different in that way
